Description

[Detailed Description of the Invention] The present invention relates to a backpack constructed so that it can be used both as a backpack for small children and as a backpack.

A variety of devices have already been put into practical use for carrying young children on their backs, including the so-called Japanese-style backpack consisting of a traditional cloth back support piece combined with a belt, and exotic backpack frames. There are also backpacks made of a combination of bags for carrying infants and children, and although each has its advantages and disadvantages, they are convenient in their own way. However, these conventional devices are generally only used for carrying young children on their backs by their guardians (parents, etc.) for so-called babysitting, or for other tasks or for carrying them on their backs when going out. It is something that Furthermore, as is well known, the riyutsuku satsuku is a satsuku that is simply carried on one's back to carry food and equipment when going on vacations or picnics, and although various types have been devised, their purpose is also limited. .

The purpose of the present invention is to propose a backpack that can be used as a backpack by taking advantage of the common features between the conventionally known functions as a backpack implement and a backpack.

That is, the present invention provides a knapsack bag comprising a pair of shoulder straps on the back side of the bag part, the bottom part of which is partially fixed so that it can be opened and closed by a slide fastener, and the bottom part is opened by the slide fastener. A crotch receiving part is provided in the center of the bag for carrying a small child in the bag.

Therefore, the backpack bag of the present invention has an opening/closing structure at the bottom.The bottom of the bag is made rectangular, and slide fasteners are sewn on three sides, leaving the back side.When the slide fasteners are opened, the bottom is released and the bag is closed. The crotch support piece attached to the center inside the bottom supports the crotch area when a small child is placed in the bag and carried on the back, so that the child can be carried on the back with the legs protruding from the bag.

In addition, the rectangular shape of the bottom of the bag according to the present invention has arcuate corners so that it can be opened and closed by attaching a slide fastener.

In another embodiment, the bottom of the backpack bag is a regular one, a slide fastener is sewn in a straight line in the horizontally long center part, and a crotch support piece of an appropriate width is attached to the center inside the bottom of the bag. By doing so, you can achieve your purpose.

Furthermore, as another embodiment, the bottom of the backpack bag is made into a rectangular bottom, leaving an appropriate width in the center, and slide fasteners are sewn on both sides symmetrically so that the three sides can be opened and closed. When the fastener is opened, the remaining bottom part becomes a crotch receiving part to achieve the purpose.

According to the present invention, when the bottom of the backpack bag is closed, it can be used as a normal backpack bag, so when going out on a picnic, for example, you can put a lunch box etc. in it and carry it on your back. When you go out with your child and your child gets tired of playing and returns home, you can empty the inside of the backpack bag and open the bottom, and the child will be placed inside the bag. The bag can be used as a bag to carry a small child on the back by straddling the pieces to support the crotch and with both legs protruding from the bottom of the bag. If you put sheets and other props in it, you can use it for storing and transporting necessary items such as lunch boxes when going on vacations or picnics, and as carrying small children on your back on the way home. Moreover, it has a great practical effect of being able to safely and reliably carry young children on their backs and reducing the burden on accompanying persons such as guardians.

The one shown in FIGS. 1 to 3 is a specific example of a backpack 1 in which the bottom of the bag is completely open. As is well known, the bag body is made up of a pair of shoulder straps 3 sewn to the back side 2', and an opening 4 is provided with a drawstring 5 by well-known means through an eyelet hole around the opening 4. This is a front hanging cover that covers the part 4, and the hanging end can be opened/closed and fixed to the bag body 2 by means of a buckle 6'.

Reference numeral 8 denotes presser belts, two of which are arranged in parallel, the length of which can be adjusted telescopically, and eggplant rings 8' are attached to each end of the belt. The eggplant rings are removably attached to hanging rings 8'' and 8'' attached to the bottom edge and shoulder of the bag body 2, respectively, so that they can be tensioned as appropriate. In addition, presser pieces 9 are sewn into appropriate positions of the bag body 2 in the portion covered by the droop cover 6 at appropriate intervals in the width direction as insertion portions for the presser belt 8.

The bottom part 10 of the bag body 2 is formed into a rectangular shape, and its back side 2' is sewn to the lower end of the body of the bag body 2.
A slide fastener 11 is sewn along the edge on the other three sides, and the bottom part 10 can be opened and closed by the fastener 11, and inside the bottom of the bag is shown in FIG.

After adjusting the bag to a comfortable condition, insert the flap cover 6 into the opening 4 as shown in FIG.
With both legs protruding from the opening at the bottom of the bag so that the crotch is supported by the crotch receiving piece 12, the presser belts 8, 8 are passed through the presser pieces 9, respectively, and placed over the shoulders of the young child in the bag. Presser belt 8,8
The eggplant ring 8' attached to the upper end is engaged with the hanging ring 8'', and the backpack bag 1 thus constructed is carried by the parent 20.

According to the spirit of the present invention, in addition to the above-mentioned specific example, the bottom and structure of the bag 2A can be constructed so that both sides of the bottom can be kept wide, as shown in FIG. If the slide fastener 14 is sewn in a horizontally long straight line on the bottom part 10', and the crotch receiving piece 12' is sewn on the inside of the bottom part of the bag body 2A in the same manner as in the above specific example, by opening the slide fastener 14, (see Figure 5), it is possible to bring about the same effects as in the case of the above-mentioned specific example.

In addition, as another specific example, as shown in FIG.
(Preferably, the size is about the same as that of the bag body.) If the slide fasteners 16 are sewn integrally with the bag body, and the slide fasteners 16 are sewn symmetrically on the bottom edge of each of the three sides on both sides, As explained in the specific example (first specific example), when used as a backpack bag for young children, by opening both slide fasteners 16, 16 provided on the bottom 10'', the bottom pieces 17, 17 can be turned downward. When hanging down, two openings are formed in the bottom 10'' as shown in FIG.
If both legs of the child placed in the bag body 2B are made to protrude from their respective openings, the bottom intermediate portion 1
5 serves as a crotch receiving piece and can provide the same effect as the above example.

It should be noted that slide fasteners such as concealed fasteners are preferred as slide fasteners used for the bottom because they are less likely to cause damage even if a soft object comes into direct or indirect contact with the pulp of a young child being carried on the back. Of course, other slide fasteners may be used as long as there is no problem.
